"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2012-228:02 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system.  The
    kernel handles the basic functions of the operating system:  memory allocation, process allocation, device
    input and output, etc.
    Security issues fixed with this release:
    CVE-2011-1020
    The proc filesystem implementation in the Linux kernel 2.6.37 and earlier does not restrict access to the
    /proc directory tree of a process after this process performs an exec of a setuid program, which allows
    local users to obtain sensitive information or cause a denial of service via open, lseek, read, and write
    system calls.
    CVE-2011-3347
    CVE-2011-3638
    No information available at the time of writing, see the CVE link below.
    CVE-2011-4110
    The user_update function in security/keys/user_defined.c in the Linux kernel 2.6 allows local users to
    cause a denial of service (NULL pointer dereference and kernel oops) via vectors related to a user-defined
    key and updating a negative key into a fully instantiated key.
    CVE-2011-1162
    The tpm_read function in the Linux kernel 2.6 does not properly clear memory, which might allow local
    users to read the results of the previous TPM command.
    CVE-2011-1577
    Heap-based buffer overflow in the is_gpt_valid function in fs/partitions/efi.c in the Linux kernel 2.6.38
    and earlier allows physically proximate attackers to cause a denial of service (OOPS) or possibly have
    unspecified other impact via a crafted size of the EFI GUID partition-table header on removable media.
    CVE-2012-0056
    The mem_write function in Linux kernel 2.6.39 and other versions, when ASLR is disabled, does not properly
    check permissions when writing to /proc/<pid>/mem, which allows local users to gain privileges by
    modifying process memory, as demonstrated by Mempodipper.
